Martin L. Greim created Thunderbunny to appear in some fan publications, before being published at Charlton. When DC bought Charlton, Greim took his creator owned character to Archie's revived imprint, Red Circle. After a couple of appearances there, Greim moved again to Warp Graphics/ Apple Comics, where he published twelve more issues of Thunderbunny. He wrote the scripts in most of the stories.
